The NORD-50 computer system is a completely integrated system of NORD-10/S and NORD-50 CPUs. The I/O system, file system and operating system are common to both processors.
The NORD-50 CPU is designed to be a fast floating point processor which is a total slave to the NORD-10/S.[1]
NORD-50 does not have an I/O system or interrupt system by itself. This implies that NORD-10/S submits jobs to NORD-50 for execution in batches and acts as a system supervisor running the operating system SINTRAN III/VS and the NORD-50 monitor.
In a NORD-50 computer system, the NORD-10/S has the following functions:
- Supervision and synchronization of the NORD-50s in the system.
- Running the operating system, SINTRAN III.
- Generating NORD-50 executable machine code via NORD-50 assembler or FORTRAN compiler.
- Being the I/O system for the NORD-50s performing I/O transfer to / from the NORD-50 memory.
CPU
The NORD-50 CPU has a word length of 32 bits.
Address space
The NORD-50 has a 4 megabytes address space.
